The 5s is the first device to ship from Apple with the company's A7 64-bit processor. It will be sold in three colors (silver, slate and gold), and includes a fingerprint scanner for security. The iPhone 5c is the first iPhone to use plastic in its design since the 3GS, and it comes in five colors (white, pink, blue, green and yellow). Storage options for both range from 16 GB to 64 GB, and pricing ranges from $99 for the cheapest iPhone 5c to $399 for the most expensive iPhone 5s (with a new, two-year contract, of course).
Despite the advancements offered by both devices, Apple continues to leave today's bleeding-edge technology out of the iPhone. Here are a few things missing that are offered by competing products.
--NFC: Near-field communications is a short-range radio technology that has a number of uses. For example, it can be used to automatically pair to Bluetooth devices, or to make mobile tap-and-go payments. Most of today's leading smartphones, such as the Samsung Galaxy Note 3, HTC One and LG G2, include NFC. Without it, Apple's iPhones will be unable to participate in mobile payment systems. Why Apple has shied away from this standardized technology is a mystery.

-- Wireless Charging: Apple continues to ignore wireless charging technology. With it, smartphone owners can place their device on a (plugged-in) charging pad. The pad then uses magnetic induction to pass a charge to the smartphone's battery. It is possible that Apple will leave this alone until it is fully standardized. Right now, three industry groups are groping for supremacy. That said, other smartphone makers, including Samsung, LG and Nokia, are including wireless charging in their devices.
-- HD Screen: Never mind how small the puny 4-inch diagonal display is on the iPhone 5s and 5c, neither screen has the ability to play full HD content. Almost all the new flagship devices announced this year, such as the One, GS4 and G2, have screens with 1920 x 1080 pixels. That makes them able to play the same high-definition content you watch on your television. Apple's iPhones stick to a non-standard 1136 x 640 pixel resolution that is incompatible with even 720p HD content, let alone 1080p.
-- Customization: As with all prior iPhones, there is no way to get inside the iPhone 5s or 5c. That means no support for additional storage in the form of microSD cards, nor a user-replaceable battery. Apple will likely never offer an iPhone with these options. If you like being able to keep a spare battery or extra memory card around, the iPhone is not for you.
